Can the fluorine-lined ball valve withstand negative pressure?

Can the fluorine-lined ball valve withstand negative pressure? The special molding process is adopted to make the sealing surface dense and good, and the combination of V-type PTFE packing makes the valve achieve zero leakage; the ball and the valve stem are cast as one, which eliminates the possibility of the valve stem being pushed out of the pressure-bearing parts due to pressure changes. Fundamentally guarantee the safety in use; adopt the all-plastic lining process, which is resistant to the strong corrosion of the medium. If the material used for the fluorine lining is polytetrafluoroethylene, its pressure range is (-0.1 ~ 6.4Mpa). However, the actual working conditions are very complicated and are generally not used.
Lianke Valve Co.,Ltd. as one who also teaches operations about how we use our whole operating system as a way to gain advantage and create considerable value and capture value in a sector where, in essence, the environment is quite hostile from a competitive point of view.
Lianke Valve Co.,Ltd. looks forward for the meeting and the association with your esteemed company.
Overall, valve application may be a great way for manufacturers to expand their use of technology, but the price could present a significant hurdle for some businesses.
